The estimation of the coastal fisheries resources quantity based on waterbirds in the Ujung Pangkah Region, Gresik Regency, East Java

Abstract

Waterbirds are a group of birds that have a high dependence on natural and artificial aquatic habitats. Its existence indicates the availability of sufficient feed at that location. This is related to bird habitat preference, which always makes feed one of the basic things to fulfill their daily needs. The Ujung Pangkah area is an estuary habitat occupied by waterbirds, both resident and migratory birds. Therefore this area provides sufficient feedstock for the existing waterbirds. Most of the aquatic bird feed is aquatic animals that live in aquatic ecosystems. This research is expected to provide a general description of the relationship between waterbirds and the number of fishery resources. The research was conducted in November 2019 in six locations in the Ujung Pangkah Region, Gresik Regency, East Java. The study results found that the waterbird population’shighest density of the was found in Kalianyar with a density of 3,878.98 ind/ha. In line with this, Kalianyar has become a high location for stocks of fishery resources. A total of 8,880,000 ind/ha benthic and 29.30 ind/ha necton were found in this location.
